Dockerfile

[samirsalem]

This needs to be tested by configuring all variables and by creating sql tables,

• A new version of apache airflow is used
• newer python libraries are used
• permissions issue with logs folder is corrected
• airflow sources are necessarily in repo in order to build the container (should this be automated before building the container?)
• Useless grafana container is removed from the build
• docker-compose up takes considerably more time for building the complete stack
